How Network APIs work in real enterprise journeys
Authentication without friction
Number Verify API automatically verifies possession of the mobile number being used, confirming that it belongs to the user’s active mobile connection without requiring manual input or one-time passwords.
Simplify authentication across key customer interactions, reduce friction, and create a smoother user experience.
Detect recycled numbers before they create risk
Number Recycle API checks whether the subscriber associated with a phone number has changed since it was last verified.
Reduce account takeover risk, protect sensitive interactions, and apply additional verification when a number may no longer belong to the original user.
Protect sensitive actions from SIM swap fraud
The API provides real-time intelligence on whether a mobile number has recently been associated with SIM change, enabling businesses to trigger alerts or additional verification for high-risk activities.
Reduce fraud while keeping onboarding and authentication smooth for trusted users.
Verify customer information with greater confidence
KYC Match API performs a secure comparison of key customer details against mobile operator data and confirms whether the information matches operator-held records.
Improve onboarding speed, reduce identity fraud risk and compliance workload, and focus additional checks where they are needed most.
